The color system of Xiguan commercial and trade culture, shaped by Guangzhou's regional climate and historical commercial and trade background, combines practicality with aesthetics, serving as a significant visual carrier of Lingnan culture. This system has inherent interdisciplinary connections with material science and environmental psychology, effectively facilitating the implementation of interdisciplinary art education courses in primary schools. By sorting out its explicit color symbols and conducting digital encoding, analyzing the implicit rules of color combinations, and exploring the mechanisms of color emotion transmission, a scientific and comprehensive curriculum system can be constructed. Through implementation paths such as cultural immersion, interdisciplinary collaboration, and work evaluation and analysis, disciplinary barriers can be broken down, helping students understand color knowledge, perceive regional culture, and achieve a profound integration of art education, cultural heritage, and multidisciplinary knowledge.
